I would like if there would be tasks for grouping up with limited till unlimited "member", depending on difficulty. I can imagine restrictions for special "Group" tasks for same race, same guild, same town, same alignment.
Same Race = some Planet related task that you can do alone or with as many friends as you have
Same Guild = Guild Competitions
Same Town = Defending (PVP)
Same Alignment = Labyrinth, where you need to be good or bad or chaotic or whatever combination to get a special result out of it.
But at the end we will know through the next 3 years, what path Dynamight want to drive with it (and us
).
I just hope, the usual groupsize will not be restricted to 4-6 Player. I wish it will be vary between 1 and undefined (restricted by serverlimits) Player.
Edit: Btw. i don't mind to group up with a tool, but rather it should give some benefits like pathfinding/tracking your member and some other magical stuff, that makes your expeditions easier.
